There is no part of this quote that can remotely be considered "cloud backup"
I have some other issues with this quote, too.
1) They are marking up the hardware costs. A 3TB NAS is a <$200 device one NewEgg; they're probably making about $50-$60 on the hardware itself. You're going to make money on the support and install, it's kind of greedy to markup hardware, too, especially if you are charging them upfront and not invoicing it.
2) I assume since they mention StorageCraft they are referring to ShadowProtect. I know this because my company deploys ShadowProtect at all of our clients. A single license of ShadowProtect 5 Virtual with Std support and one year of maintenance is $395. In fact, StorageCraft NEVER charges a monthly fee, it's a one time charge. They also don't mention how many licenses.
3) As far as off-site backup, I'm not a fan of paying a company to host it off-site on their hardware, I'd prefer to use a cloud solution or have my own DR server off-site to backup to. But at $360/yr it's not the biggest crime on this quote.
4) The installation price is inline with what it should be, it's the only part of this quote that I don't have a problem with.
It would help if I knew how big their company was and how many servers or VMs they are running.
